To all whom it may concern:

Be it known that I, EDWARD I. BRADDOCK,

a citizen of the United States, residing in Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement in' Methods of and Apparatus for Making Vire Nails and like Articles, of which the following description, in connection with the accompanying drawings,

is a specification, like characters on the drawings representing like parts.

This invention relates to the manufacture of malleable metal articles and hasfor its object the conversion of metal stock into duplicate finished products rapidly and economically. addressed to the manufacture of nails and the like from wire or bar stock, and is herein exemplified by a machine and method for making headed, tapered and pointed wire nails. Thus, in its general aspects the invention consists of a method and machine for making duplicate malleable metal objects of whatever character and specific de- 5 scription, provided. they are susceptibleof fabrication by continuous roll-forging methods and mechanism, operating on metal stock or metal blanks; and in its specific aspect consists of a. method and machine for automatically fabricating nails.

For illustration, the metal blankmay be a wire blank and the headed articles produced therefrom may and preferably will beheaded wire nails and particularly headed wire nails of novel construction, as will be described.

To facilitate description, the metalblank will be hereinafter designated a wire blank and the headed article awire nail. In accordance with the novel method, the wire blank is compressed in the direction ofits length to form heads at the opposite ends thereof, and the headed blank thus'formed is elongated by rollin the desired amount, and is then severed su stantially at its longitudinal center to form duplicate nails.

The elongated headed blank-is preferably provided with oppositely extended tapering portions and with point forming recesses substantially at right angles to the said Particularly, the invention is taperingportions between the latter, and is..';

severed substantially at the center of said point forming recesses to form duplicate L ointed nails of novel construction, as will described. A

' 5 a preferred construction of novel appa-:

ratus -will be hereinafter described, wltlh which the novel nails may be produced in accordance with the novel method re ferred to.

The preferred form of apparatus herein shown is provided with mechanism for straightening the wire as it comes from a coil of wire with mechanism for feeding the straightened wire to mechanism for cutting the wire into wire blanks; with mechanism for transferring the wire blank to mechanism b which it is firmly held while-it is.

being eaded .at its opposite ends; with mechanism for delivering the headed wire blanks into a runway, through which they are fed to mechanism by which they are elongated, tapered in opposite directions, compressed to further elongate them and provide them with point-forming recesses; and severed to form duplicate pointed wire nails.

These and other features of this invention will be pointed out in the claims atrthe end of this specification.
